ROAD CONSTRUCTION.

Application filed December 13, 1921.

To all whom it may concern:

Be it known that 1, DAVID W. Bown, a citizen of the United States,residing at Detroit, in the county oflVayne and State of Michigan, haveinvented new and useful Improvements in Road Constructions, of which thefollowing is a specification.

This invention has reference to road constructions, and moreparticularly to novel means designed for securing the reinforcingelements of a road bed formed of plastic material while the same arebeing properly positioned.

An object of the invention is to provide stakes of novel constructionfor supporting the side forms and reinforcing elements of the road bed.

A still further object of the invention is to provide a flexible baseboard which will conform to the contour of a road crown.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the in vention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings Figure 1 is a fragment-a1 plan view ofreinforcing elements disclosing the same as positioned prior to thepouring of the cement or plastic material.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3is an end elevational view dis closing the portable supports aspositioned prior to securing the same.

Figure 4 is a sectional view taken on line 4-4 of Figure 2.

Referring to the drawings in detail, the invention embodies base boards5 which are formed of any suitable material having flexible qualities sothat the same will conform to the contour of the crown of a road, thelengths of the boards 5 being equal to the width of the road to beconstructed.

These boards 5 are disposed in spaced relation with each otherthroughout the length of the road bed, and-as shown, each of these baseboards is provided with a groove 6 formed intermediate the side edgesthereof and extending throughout the lengths thereof.

Serial No. 522,096.

Side forms 7 form parts of the construction, and are provided with cutout portions to accommodate the base boards 5, and engage the sameadjacent to the outer ends of the boards 5 to eliminate lateral movementof the boards with respect to the side forms. Reinforcing rods indicatedat 7 are positioned longitudinally of the road bed and are disposed atvarious levels to reinforce the road bed at points adjacent to the uppersur face thereof as well as at the base thereof.

Positioned between the side forms 7 are the portable supports 8 whichare substantially triangular in formation and provided with suitablerecessed portions to accommodate the rods 7 to support the same in theirproper position prior to application of the rods to brace bars 9 and 10,which form a permanent part of the road reinforcing structure. Thesebars 9 and 10 are provided. with openings to accommodate the rods 7, andas shown the bars 9 are disposed at angles with respect to the baseboard 5, the lower ends of the bars 9 being disposed in the grooves 6 ofthe base board 5.

The lower extremities of the brace bars 9 are supported in properspacedrelation with each other, as by means of the brace bars 10 which connectwith the rods 7 adjacent to the base boards 5. Angle bars or crown barsare indicated at 11 and are designed to embrace the upper ends of thebrace bars 9 to secure the same against movement. These crown bars areheld in position as by means of the side forms and also by stakes 12which have angular arms 13 conforming to the angles of the crown bars toinsure a close engagement between the crown bars and arms 13 to preventmovement of the crown bars with respect to the arms 13.

The side forms are held in vertical positions as by means of the stakes14, which are provided with right angled arms 15 especially designed toembrace portions of the upper edges of the side forms 7. 'lransverselyextending rods 16 also form a part of the reinforcing construction andare held in position as by means of the side forms 7, and are alsoconnected with the longitudinal rods as by means of wire securingmembers 17 which are constructed of wire looped around adjacent portionsof the rods and twisted in a manner to secure the same in position.

In construction of a road bed the base boards are positioned properdistances a art, andside forms 7 are now positioned a ong the outeredges of the road construction and secured in position by means of thestakes 14. The rods 7 are now positioned on the portable supports anddrawn from same through the brace bars 9 and 10, and secured inposition.

After the rods and bars 9 have been properly positioned, the ends of thebars 9 are positioned in the grooves of the base boards The stakes 12are now secured over the crown bars to secure the same against movement,after which the plastic material or cement may be poured around thereinforcing structure. Prior to the setting of the plastic material, thecrown bars and stakes 12 are removed for further use.

Having thus described the invention, what is claimed as new is 1. A roadconstruction embodying longitudinal and transversely extendingreinforcing rods, base boards having grooves, brace bars connected tothe reinforcing rods and having their lower ends disposed in thegrooves, and portable supports for support ing the rods prior to theapplication of the reinforcing bars.

2. A road construction embodying longithe crown of a road, transverselyextending bars connecting the rods for securing the same in properspaced relation with .each other, angular brace bars connecting therods, a crown bar including angular surfaces and means embracingportions of the crown bar for securing the structure in an uprightposition.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signa ture in the presence of two Witnesses.

DAVID W. BOWE.
